The Node.ownerDocument read-only property returns the top-level document object for this node.
Syntax
document = element.ownerDocument
documentis thedocumentobject parent of the current element.
Example
// given a node "p", get the top-level HTML child // of the document object var d = p.ownerDocument; var html = d.documentElement;
Notes
The document object returned by this property is the main object with which all the child nodes in the actual HTML document are created. If this property is used on a node that is itself a document, the result is null.

[1] Starting in Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6), the ownerDocument of doctype nodes (that is, nodes for which Node.nodeType is Node.DOCUMENT_TYPE_NODE or 10) is no longer null. Instead, the ownerDocument is the document on which document.implementation.createDocumentType() was called.
